Title: Automatically calibrated radar altitude control
IPC: G01S13/935
Filed: 1960-03-15
Abstract: 945,548. Radar altimeters. UNITED AIRCRAFT CORPORATION. March 15, 1960 [May 11, 1959], No. 9044/60. Heading H4D. Relates to a pulse radar altimeter comprising a transmitter 18 and receiver 32 coupled through a duplexer 20 and switch 22 to a directional aerial 14 producing a beam directed downwards towards the ground ahead of of the aircraft, Fig. 1 (not shown), in which a voltage proportional to the intensity of the echo signal is subtracted in a comparator 64 from a voltage representing a predetermined fraction of the intensity of the transmitted signal to give a command signal representing the deviation of the aircraft from a predetermined altitude relative to the terrain ahead of the aircraft, said predetermined fraction being determined by the manual setting of a potentiometer 58; the command signal may be applied to automatically control the altitude of the aircraft. According to the present invention errors due to variations in the reflectivity of the terrain are compensated by automatically controlling the potentiometer 58 by a control signal representing the deviation of the aircraft from a predetermined altitude as measured relative to the terrain directly beneath the aircraft by a conventional radio altimeter 68 whose operation is independent of the reflectivity of the terrain. As shown, the control signal is derived in a comparator 76 as the difference between the voltage from a manually set potentiometer 80 representing the predetermined altitude and the output from the radio altimeter 68, the control signal being fed to a servomotor 90 controlling the potentiometer 58. The voltages representing the intensities of the transmitted and echo signals produced by the radar 18, 32 are obtained by alternately coupling the output from the receiver 32 to two integrators 44, 46 by means of a switch 34, the output from the transmitter 18 being alternately coupled to the aerial 14 and an echo box 30 by a switch 24 synchronized with the switch 34. Switches 24 and 34 may be waveguide switches.

Title: Probes for providing simulated sonar signals to test distance measuring equipment
IPC: G01S7/52
Filed: 1975-03-06
Abstract: 1498278 Testing pulse-echo equipment SIMRAD AS 6 March 1975 [7 March 1974] 9407/75 Heading G1G A probe for providing simulated sonar signals for testing sonar apparatus draws power from transmitter pulses of the apparatus, generates in response to a transmitter pulse two dissimilar control signals, and uses the latter signals to modulate a carrier frequency oscillator to obtain two simulated sonar signals. In the Fig. 2 embodiment for testing an echosounder, the probe is connected at terminal 1 to the sounding transducer. Transmission pulses are rectified at 14 to build up a voltage on capacitor 19. This voltage is limited by reference diode 18 and SCR 16 to form the supply for the circuits in the probe. The supply current is limited by FET 21. Each transmission pulse triggers a monostable circuit 26, 28 which in turn applies pulses to RC networks 33, 34 and 39, 40 to produce at the output of gate 37 two delayed pulses corresponding to a simulated fish-echo and sea-bed echo respectively. The delayed pulses gate on an oscillator 41, 42 operating at the echo-sounder's carrier frequency. The relative amplitudes of the two resulting bursts of oscillation are controlled by resistors 47, 50 and FET 49 to provide simulated echo signals which are fed to terminal 1. A switch 8 enables oscillator 41, 42 to be kept on continuously for checking time-varied-gain functions in the echo-sounding receiver. The strength of the echo-sounding transmission pulses is monitored by LED's 10 and a neon 12, which light up at low and high voltages respectively. It is stated that the invention is applicable also to testing FM or coded-pulse transmission systems, and Doppler logs.

Title: Refractory metal production process
IPC: C22B34/12
Filed: 1956-03-27
Abstract: The reduction of a halide of Ti, Zr, Hf, Nb, V or Ta is effected by injecting it as a liquid into a bath of molten alkali metal until it is in excess, so that subhalides are formed, and then injecting further alkali metal sufficient to effect complete reduction to the metal.  In an example molten sodium beneath an atmosphere of argon is raised to about 400 DEG C. and twice the stochiometric amount of TiCl4 injected through a nozzle in the reactor lid, the temperature rising to 850 DEG C., the further necessary molten sodium to obtain the desired stochiometric ratio is then injected beneath the melt surface, the temperature being kept between 850 DEG C. and 950 DEG C. until the reaction is complete. The sodium bath may initially also contain some sodium chloride.
